Sulphuric Acid Cannon
The Sulphuric Acid Cannon is a post-Moon Lord gun that is dropped by the Mauler after Polterghast has been defeated. It fires sulphuric orbs at enemies. The bubbles shot by this weapon will stick on to enemies hit. After a few seconds, sulphuric mist puffs will occasionally fly out from the orbs in random directions.
The bubbles shot by this weapon inflict Venom on contact with enemies and sticks to them. Unlike most weapons that deal Venom, the damage over time dealt by the bubbles stack. Up to four bubbles can be attached on an enemy at once, similar to Daybreak spears for a maximum of 200 damage per second. This can stack with the Lionfish for a maximum of 500 damage per second. The sulphuric mist puffs do not inflict a modified Venom debuff and deal 6 damage per second as usual.
Its best modifier is Unreal.
